OK, here's what we can do to fix this:

1) Put back -pthread in -current so all the ports don't fail

2) I will build a full set of -current packages with the -pthread
error still in place, to determine the list of packages that need to
be fixed (in fact I already have this, see
http://dosirak.kr.freebsd.org/errorlogs).

3) You, John Birrell, and whoever else is interested in fixing these
ports can work on them at your own pace without disrupting life for
the rest of the users.  Once they're all fixed, we can turn the error
back on or make it a NOP or do whatever else is decided to be
appropriate.

4) It is likely that steps 2 and 3 will need to be iterated several
times, because there are dozens of ports that need to be fixed, and
many of them are hiding other ports that depend on them and also need
to be fixed.
